PROBLEM TO BE SOLVED: To prevent a fraudulent act for acquiring value larger than value of a privilege corresponding to a progress situation of a game by allowing a performance control means to disable reception of control signals from game control means.SOLUTION: An identical voltage generation circuit 306 supplies a supply voltage to a sub-control unit 91 and a command transmission line 312. When the command transmission line 312 is short-circuited, supply of the supply voltage to the sub-control unit 91 is also stopped, and drive of the sub-control unit 91 is stopped. Therefore, the command transmission line 312 is short-circuited to allow the sub-control unit 91 to disable reception of commands, and the sub-control unit 91 is allowed to erroneously recognize, for example the number of continuous winning times of a specified winning symbol combinations and the number of navigation performances, thus preventing determination of the number of games of AT and the number of navigation stocks. |
